Pls ans both the questions im very confused

Step-by-step explanation:

In Δ PQS and ΔPQT

∠QPS = ∠RPT       {Common angle}

∠PSQ = ∠PTR = 90°         {QS & RT are altitude}

QS = RT                            {given}

ΔPQS ≅ ΔPRT               {A A S congruent}

PQ = PS                         {CPCT}

So, PQR is an isosceles triangle.

9)

a) Flas card (I) and (iii) are congruent.

b)  A S A congruent

c) BC ≅ RP

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
